Editor's Notes
- The real power of adaptive bitrate streaming is that it “adapts”. When a video file is encoded to adaptive format, it is broken up into segments. More Information Adaptive Bitrate Streaming on Wikipedia: https://en.wikipedia.org/wiki/Adaptive_bitrate_streaming What is Adaptive Bitrate Streaming (ABS) in YouTube: https://www.youtube.com/watch?v=z1m9NadpGAg
- Dynamic Packaging and origin service. Enables us to deliver live and VOD content directly to a client player app using common protocols Streaming Endpoints (Origin) - Azure Media Services | Microsoft Docs Dynamic packaging in Azure Media Services v3 - Azure Media Services | Microsoft Docs HLS protocol HLS V4 HLS V3 HLS CMAF MPEG-DASH protocol MPEG-DASH CSF MPEG-DASH CMAF Smooth Streaming protocol Smooth Streaming Smooth Streaming 2.0 (legacy manifest)
- Ajustar la ventana de presentación es mas que nada para escenarios Live. Los usuarios cuando se unen a ver un live stream, siempre arrancan en el live edge. Hay casos donde vos queres permitirle al usuario hacer seek back en la timeline del player para que pueda ver lo que paso antes, o poner pausa y seguir viendo. Para lograr esto se necesita que el live stream tenga un ventana de archive o DVR (puede llegar a ser de varias horas). Si por el contrario, vos no queres que tus usuarios abandonen el live edge tenes que de alguna forma eliminar/limitar la timeline del player que contiene la ventana de archive o DVR. https://docs.microsoft.com/en-us/azure/media-services/latest/filters-concept#presentationtimerange
